How to Activate Double Authentication on Twitter

These and the ones to come are the years of the digital era, where your real identity becomes one with your online presence. For this reason, it’s very important to protect your access online, defending your accounts from potential thiefs.

Today, I am going to show you how to activate double authentication on Twitter, a tool recently adopted by the notorious social network that asks for a verification code everytime you log in. It may seem like an annoying thing, but you won’t regret it. Let’s see how to do it.

If you want to know how to activate double authentication on Twitter, the first thing you have got to do is visit the homepage of the social network and click on the Gear icon on the top-right, then on Settings from the menu that appears.

At this point, scroll down the page untill you see the item Account Security and check the voice “Require a verification code when I sign in.“. If you can’t check it, it’s because you haven’t linked a phone number to your account yet.

In order to link a phone to Twitter, click on the underneath link “add a phone” and, in the window that opens, fill out the form with your Country, Phone Number, and Carrier. Click then on Activate phone.

At this point, you will be asked to send a text message to a certain number, just do it and wait for the page to refresh. You can now select how to use the text service, I highly suggest to remove all the options if you have a smartphone, as you can already do everything with the mobile app of Twitter. If you change something, click on Save Changes.

Now that you have added a phone number to Twitter, click on Account on the left sidebar and scroll down again untill you find the item Account Security and check the voice next to it, as we have seen before.

You will be prompted a window, simply click Okay, send me a message. In the next window, before clicking Yes, make sure you have received the text message. If you haven’t yet, click No and repeat the procedure (perhaps trying logging out and in again if it keeps not working). Once you click yes, type in your password and click on Save Changes.

Everytime you log in, from now on, you will be asked for a code that will be automatically sent to your phone. If you want to remove this option, Click on the gear icon on the top-right, scroll down and uncheck the item “Require a verification code when I sign in.”. Click then on Save changes, insert your password, and click on Save changes again.
